Customer clustering analysis

This notebook presents a comprehensive analysis of customer segmentation using clustering techniques. The goal of this analysis is to identify distinct groups of customers based on their behaviors, which can help in understanding the underlying patterns within the customer base and optimizing marketing strategies. By leveraging clustering methods, we aim to identify meaningful customer segments, and subsequently, we use classification techniques to explore how demographic variables can predict cluster membership.

The dataset used for this analysis, titled "Customer Personality Analysis," was sourced from Kaggle and provides a range of customer attributes, including demographic information, product preferences, and spending habits. By applying different clustering methods, we aim to uncover meaningful customer segments that can inform targeted marketing and personalization efforts.

In this notebook, we will walk through the following steps:

1. Data Import and Preprocessing: We start by importing the dataset and performing necessary preprocessing steps, including handling missing values, encoding categorical features, and scaling the data.
2. Exploratory Data Analysis (EDA): A visual and statistical exploration of the data to understand the distribution and relationships between variables.
3. PCA: Reducing dimensionality
4. Clustering Analysis: Application of clustering algorithms such as K-Means and Agglomerative Clustering to segment the customers into distinct groups based on spending habits.
5. Model Evaluation: Assessment of the clustering results using metrics like silhouette score to determine the optimal number of clusters.
6. Classification: After identifying clusters, we employ classification models to predict cluster membership based on demographic features such as age, income, and education level. This step aims to understand how demographic factors relate to the behavioral clusters identified earlier.
7. Conclusion and Insights: Summary of the findings and insights derived from the clustering analysis, along with potential implications for marketing strategies.
   This analysis aims to provide valuable insights into customer behavior, enabling businesses to tailor their marketing efforts and enhance customer satisfaction. For example, instead of spending money to market a new product to every customer in the company’s database, a company can analyze which customer segment is most likely to buy the product and then market the product only on that particular segment

0	3	8	10	4
1	2	1	1	2
2	1	8	2	10

product_titles=[]
product_charts=[]

Store Purchases are the most frequent, followed by Web purchases.

alt.Chart(data).mark_point().encode(
    alt.X(alt.repeat("column"), type='quantitative'),
    alt.Y(alt.repeat("row"), type='quantitative')

We will summarize the information in a 'promo' variable, storing the sum of the response in every campaign.

data['promo'] = data[promotion].sum(axis=1)

Correlation matrix

columns = product + place + ['product_sum', 'promo']

corr_mat = data[columns].corr().reset_index().melt(id_vars='index')
heat_map = alt.Chart(corr_mat, title='Correlation Matrix').mark_rect().encode(
    alt.X('index:N'),
    alt.Y('variable:N'),
    alt.Color('value:Q', scale=alt.Scale(scheme='viridis')),
).properties(
    width=750,
    height=750
)

text = alt.Chart(corr_mat).mark_text(baseline='middle').encode(
    alt.Text('value:Q', format=".2f"),
    alt.X('index:N'),
    alt.Y('variable:N')
)

heat_map + text

Summing up:

• the Wines amount is negatively correlated to the amounts of all the other categories of products.
• the product_sum (total amount of spending) is strongly correlated to NumCatalogPurchases and negatively correlated to NumDealsPurchases.
• NumWebPurchases is negatevely correlated to NumStorePurchases.
• MntGoldProds is negatevely correlated to prosuct_sum.

Preprocessing

Selecting variables for clustering

We want to conduct clustering based on a subgroup of variables that describe the spending behaviours of the customer.

columns = product + place + ['product_sum', 'promo']
X = data[columns]

Standardize features by removing the mean and scaling to unit variance.

scaler_std = StandardScaler()
X_std = scaler_std.fit_transform(X)

Dimensional reduction

pca = PCA().fit(X_std)

ex_var_ratio =pd.DataFrame(enumerate(np.cumsum(pca.explained_variance_ratio_)), columns=['Principal Component', 'Cumulative Explained Variance'])
baseplt = alt.Chart(ex_var_ratio).mark_line().encode(
    x='Principal Component',
    y='Cumulative Explained Variance',)
baseplt+alt.Chart(ex_var_ratio).mark_line(color='red').encode(
    y=alt.datum(0.9),
    x=alt.X('Principal Component:Q')
)

for i,x in enumerate(pca.explained_variance_ratio_.cumsum()):
  if x > 0.9:
    print(f'N components: {i}')
    break
X_reduced = PCA(n_components=i, random_state=11).fit_transform(X_std)

N components: 7

Determine the number of clusters to be formed

We use the elbow method and the silhouette score to choose the best number of clusters. We perform the clustering using Kmeans algorithm for different values of k, then compare the results on charts.

sse = {}
sil = []
for k in range(2, 18):
  kmeans = KMeans(n_clusters = k, random_state=29).fit(X_reduced)
  sil.append(silhouette_score(X_reduced, kmeans.labels_, metric = 'euclidean'))
  sse[k] = kmeans.inertia_
sil_df = pd.DataFrame(enumerate(sil), columns=['k', 'value']).assign(method='Silhouette score')
elb_df = pd.DataFrame(sse.items(), columns=['k', 'value']).assign(method='Elbow')

alt.Chart(pd.concat([sil_df, elb_df]).reset_index(drop=True)).mark_line().encode(
    x='k',
    y='value',
    color='method'
    ).facet('method', columns=1
            ).resolve_axis(
                y='independent'
            ).resolve_scale(
                y='independent'
            )

3 clusters seems to be a reasonable choice looking at the charts.

Hierarchical Clustering

We want to create clusters of clients based on their spending behaviour, then we want to use classification based on the demographic to predict customer's cluster. Conducting the analysis at the end we get that the best overall performance is obtained clustering in 3 groups. The 3 groups will result well defined and distinct in behaviours and in demographic characteristics.

hclust = AgglomerativeClustering(n_clusters = 3).fit_predict(X_reduced)
data['cluster'] = hclust

product_chart = alt.Chart(data).mark_boxplot().encode(
    alt.Y(alt.repeat("column"), type='quantitative', scale=alt.Scale(type='sqrt')),
    alt.X('cluster:N'),
    alt.Color('cluster:N')
).repeat(
    column=list(product)
).resolve_scale(
    y='shared'
)

sum_product_chart = alt.Chart(data).mark_bar().encode(
    alt.X('mean(product_sum):Q'),
    alt.Y('cluster:N'),
    alt.Color('cluster:N')
)

product_chart & sum_product_chart

Cluster 0: High Expenditure (preferencies: Wine and Meat)
Cluster 1: Low Expenditure (preferencies: Gold and Meat) this is the more balanced group
Cluster 2: Medium Expenditure (preferencies: Wine and Meat)

promo_chart = alt.Chart(data).mark_bar().encode(
    alt.X('mean(promo):Q'),
    alt.Y('cluster:N'),
    alt.Color('cluster:N')
)
promo_chart

The chart is similar to the Mean of product_sum chart, but the differences between groups are reduced, suggesting the following:
Group 0: low attention to promotions
Group 1: high attention to promotions
Group 2: medium attention to promotions

place_chart = alt.Chart(data).mark_boxplot().encode(
    alt.Y(alt.repeat("column"), type='quantitative', scale=alt.Scale(type='sqrt')),
    alt.X('cluster:N'),
    alt.Color('cluster:N')
).repeat(
    column=list(place)
).resolve_scale(
    y='shared'
)
place_chart

Group 0: Low deals purchases and high Catalog Purchases
Group 1: High deals purchases
Group 2: Medium deals purchases
Note: Group 2 has a small higher percentage of Web Purchases

Conclusions

In this notebook, we conducted a comprehensive analysis of customer segmentation through clustering techniques and subsequently explored the relationship between these clusters and demographic variables. The clustering analysis successfully identified distinct customer groups, each characterized by unique purchasing behaviors and preferences.
Following the clustering, a classification analysis based on demographic features such as age, income, and education level revealed significant relationships between these variables and the identified clusters. This connection between demographic factors and customer behavior underscores the importance of personalized marketing strategies.
The results of this analysis can be used to enhance targeted marketing efforts, improve customer engagement, and ultimately drive business growth. By understanding the specific needs and preferences of different customer segments, companies can tailor their offerings and communications more effectively.
